The correct answer is option 3: USA. Since the fiscal year 2014-15, India has consistently had a trade surplus with the United States.

A trade surplus occurs when the value of a country`s exports exceeds the value of its imports. In this case, India has exported more goods and services to the United States than it has imported from the country.

Option 1: China is not the correct answer. India has actually had a trade deficit with China for several years, meaning that the value of India`s imports from China has been greater than the value of its exports to China.

Option 2: Saudi Arabia is also not the correct answer. India has had a trade deficit with Saudi Arabia, meaning that the value of India`s imports from Saudi Arabia has exceeded the value of its exports to the country.

Option 4: Germany is not the correct answer either. India has had a trade deficit with Germany, with the value of India`s imports from Germany being higher than the value of its exports to the country.

Therefore, the correct answer is option 3: USA, as India has consistently had a trade surplus with the United States since 2014-15.
